I blocked a creature with menace with two creatures. I then tried to cast a spell to give one of them indestructible. He had already chose which to deal damage to first which I assumed was the top card. It wasn't. I've had this issue before. Maybe there should be something that designates which one is receiving damage first. There was a gold arrow to the one I choose but it didn't matter. Also the creatures I blocked with were the same card. I don't know if that's the issue. Either way, fix it!
